Having suffered through a 3 hour frustrating mall shopping expedition, my DD and I validated that American Eagle cannot accomodate a skater butt, nor can Hollister, however, Abercrombie and Fitch boot cut work well for both skater butt and skater thigh (you're female, right?)
To get them to cover the skater butt and thigh on the non A&F jeans, the waist was so loose that ... ummm ... they slid low enough to show ... the skater butt in full glory.
Levis, however, accomodate my proportions, that are similar to hers, but, through sloth not through skating. I hunt for the curvy silhouette ones, and bootcuts. Very accomodating
